MACHINERY FOR MANUFACTURING CASKS} on BARRELS.

SPECIFICATION forming part of Letters Patent No. 606,516, dated June 28, 1898. Application filed December 24,1897. Serial No. 663,366. (No model.) Patentedin England July 28, 1896, Ito-16,670.

To all whom it may concern:

Be it known that 1, ROBERT COLLEN, engineer, a subject of the Queen of Great Britain and Ireland, residing at 30 Pigott street, Limehouse, in the city of London, England, have invented certain Improvements in Machinery for Manufacturing Oasks or Barrels, (for which I have, in conjunction with George Mills, deceased, late of Castor street, Poplar, in the said city of London, obtained a patent in Great Britain, No. 16,670, dated J'uly28, 1896,) of which the following is a specification.

This invention has for its object to provide a machine, herein for convenience termed a crozing-maohine, for use in the manufacture of casks or barrels and which at a single operation effects the crozing, chiming, and jiggering operations-that is to say, forms the grooves or crozes into which the heads are fitted, chamfers or rounds off the ends of the staves, and levels the inner faces of the staves adjacent to the crozes.

The apparatusherein described is applicable for use in the manufacture of vessels or bodies other than those ordinarily known as casks-for example, tubs, vats, tubes, or the like-and I wish it to be understood that whenever in this specification and claims the context admits of such an interpretation the word cask or oasks is intended to include all such structures.

The invention will be best understood b reference tothe accompanying drawings, in which- Figure 1 is a front elevation'shown partly in section, and Fig. 2 a side elevation, of-the improved erozing-machine. Fig. 3 is a vertical section on the'line 3 3 of Fig. 2, but drawn to a scale larger than that to whichFigI 2 is drawn. Fig. i is an under side view of the cutter-head shown in Figs. 1, 2, and 3, drawn to a scale the sameas that to which Fig. 3 is drawn. Figs 5 and 6 are respectively an under side view and an elevation of the table. Fig. 7 is aplan of the lower cone of the crozingmachine; and Figs. 8 and 9 are views, partly in elevation and partly in section, of upper and lower cone-rings, respectively, applicable to the crozingmachine, as hereinafter described.

Like letters of referenceindicatelike parts ram Q, of which only a part is shown.

throughout the several figures of the drawings. I I

The crozing-machine, as shown in Figs. 1 and 2, comprisesa-stationary frame 0, in the upper part of which is mounted a revolving vertical shaft P, and at the lower part is provided a circular frame or cone Q, hereinafter termed the lower cone, capable of being moved upward on guide-bars o by a hydraulic If desired,the lower cone may be raised by power other than hydraulic. Another circular frame or cone Q hereinafter termed the upper cone, is adjustably secured on the guide-bars 0, which are screw-threaded for a portion of their length for example, by nuts 0 and clamping-screws 0 of which latter only one is shown, though there may be one such screw for each of the two front bars or for each of the three bars 0. The upper cone Q is generally secured a little belowjthe level of the cutter-head 1?, which is secured to the lower end of the revolving shaft 1?. Within the lower cone Q is fitted a'table q,Figs. 1, 2, 5, and 6, which when the said lower cone is in its lowermost position, as shown in full lines in Figs. 1 and 2, extends above the level of the said cone, the, legs q of the table then resting on the base-plate O or other suitable surface. When the lower cone Q is raised, the table q'is received in the interior of the said cone, as indicated in dot-and-dash lines in Fig. 1. The last-described arrangement provides a readier means of getting the cask or barrel B, Fig. 1, into position than would be the case if'the cask or barrel had to be lifted into and out of the lower cone Q at the beginning and termination of the operations. The cutter-head P carries tools or cutters p p (the former forked, as shown, and the latter having a straight chisel edge) for forming the croze or groove for receiving the caskhead, preferablytwo diametrically opposite tools 19 for effecting the chiming operation, and a tool pifor' effecting the jiggering operation, all of which operations are carried out simultaneously. The tools or cutters p, p, 19

and p are detachably secured to tool-carriers p engaging with screw-threaded shafts 10 all connected by bevel-gearing p to a vertical shaft S, hereinafter termed the inner or first driven shaft P by bevel or other gearing P and near the upper end of the inner shaft S is loosely mounted a pulleys, rotated by a belt 8, driven from the main shaft P and on a conveniently left-handed screwthreaded collar S, Fig. 3, at a lower part of the said inner shaft is S, which is preferably secured a hand-wheel formed with a wooden rim, as indicated in Fig. 3, or is. otherwise made as light as practicable, so that it may not acquire appreciable momentum when r0 tated or present appreciable inertia when about to be rotated, by which means the jamming of the screw-threaded shafts p in their nuts is prevented.

On the upper end of the inner shaft S is secured a conical friction-cup S having its mouth or open end presented downward and adapted to receive the upper and conical end of the boss of the above-mentioned pulley s. is provided with an upconical friction-cup S The hand-wheel S wardly extending adapted to receive the lower and taper end of a non-rotating split sleeve S whose two parts 5 are connected together near their upper ends by blade-springs 3 which when the sleeve S is clear of the cup 8 hold the two parts 8 out of contact with the inner shaft S and which yield sufliciently to admit of the two said sleeve parts gripping the inner shaft when they are forced downward into the fric- The split sleeve S which, as it tion-cup S. were, constitutes a brake for the shaft S, is

pivoted in or to a fork S", which may be raised and lowered by means of a hand-lever The pulley s rotates in the same direction as but at a higher speed than the cutter-shaft P, so that when the fork S is raised and the boss of the pulley s is consequently forced into the cup S, the inner shaft S will outrun the cutter-shaft P and through the bevel-gearing 19 and screw-threaded shafts 13 cause the tools or cutters p p p p to be moved inward. When the forkS is lowered, and the split sleeve S is consequently forced into the friction-cu p S, the inner shaft S is retarded or prevented from rotating," so that during the cutter-head P (the further rotation of the screw-threaded shafts 19 being carried around bodily with the said cutter-head) the tools or cutters pp 19 19 are moved outward. As the engagement of the sleeve S with the cup S and of the pulleys with the cup S is frictional, these parts slip over each other when the limits of the inward and outward movements of the tools or cutters are reached, even though the lever s be retained in either of end of the cask into its two operative positions. When the lever S is free, both of the before-described friction devices are disengaged and the inner shaft rotates at the same speed as the cuttershaft, so that the tools or cutters rotate with the cutter-head without being moved radially therein. j

To reduce friction, I prefer to provide ballbearings T between the upper end of the cutter-shaft Pand the collar S and between the upper end of the split sleeve S and the pulley s.

hen the last-described machine is at work,

the cutter-head P is kept constantly rotating,

andv the previously-trussed cask or barrel R to be operated upon has first introducedinto it an india rubber diaphragm, which fits tightly into its interior, for the purpose of preventing the shavings from falling through the said cask or barrel onto the lower cone Q or parts adjacent thereto. The cask is then placed on the table q and the lower cone Q raised by the ram Q, which forces the upper properly centers the cask and retains it in position.v The before-mentioned split sleeve S is then vent the rotation of the inner shaft S, and thereby, as previously described, cause the cutters to move outward to effect the cutting operations, and afterward the split sleeve is raised so as to cause the cutters to be moved inward, therelative speeds of rotation of the cutter-shaft P and pulley 5 being preferably such that the cutters are caused to move slowly outward and quicker inward. The lower cone Q is then allowed or caused to descend, and the cask or barrel R is then successively removed from the table q and empthe upper cone Q and depressed, so as to retard or pretied of the shavings, inverted, and replaced on the table, after which the before-described operation is repeated.

\Vhen it is desired to employ the crozing' machine for casks of a smaller size than that which the before-described cones are adapted to receive, other cones or rings U U, Figs. 8 and 9, of smaller diameter may be fitted in those first described. The removable upper cone or ring U is provided with an annular shoulder to, with which bolts or screws in the upper cone Q may engage to retain it in position therein, and the removable lower cone or ring U is adapted to remain in position merely by its own weight and to receive a table smaller than that fitting directly into the lower cone Q.

To limit the extent to which the tools are to cut into the cask or barrel,readily-removable stops V, Fig. 3, of varying thicknesses may be provided in the guides or slots P", in which the said tools or their holders move radially outward and inward in the cutter-head P. The tools maybe moved outward and inward for adjustment when the machine is at rest by rotating the hand-wheel S Having now particularly described and as certained the nature of this invention and in what manner the same is to be performed, I

declare that what I claim is- 1. In a crozing-machine, the combination of a revolving head carrying tools or cutters for effecting the crozing, chiming and jiggering operations, automatic mechanism capable of giving said cutters radial movement either inward or outward with relation to the cutter-head, and means under the control of the operator and capable of causing said mechanism to operate to produce either of said radial movements of the cutters, substantially as described.

2. In a crozing-machine, a revolving cutterof altering the rate of speed of one shaft with relation to the other whereby the radial movements of the tools are effected, substantially as described.

4. In a crozing-machine, a revolving cuttershaft, cutting-tools supported thereby, an independently -rotatable shaft effecting the movement of the cutting-tools to and from their work,means imparting differential speed revolutionsto the two shafts, means capable of varying the rate of speed of one of the shafts substantially as described.

5. In a crozing-machine, a revolving cuttershaft, cutting-tools supported thereby, a second shaft concentric with, the cutter-shaft and controlling the movement of the tools to and from their work, means causing one shaft to'revolve faster than the other, and means for altering the rate of speed of one of the shafts to make it rotate either faster or slower than the other shaft, substantially asdescribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

It. COLLEN.
